Todd Kerpelman	0bff399af1	Make metadata from the url_selenium loader match that of the web_base loader (#11617) ... **Description:** I noticed the metadata returned by the url_selenium loader was missing several values included by the web_base loader.

Ash Vardanian	1acfe86353	Accelerating Math Utils with SimSIMD (#11566) ... LangChain relies on NumPy to compute cosine distances, which becomes a bottleneck with the growing dimensionality and number of embeddings. To avoid this bottleneck, in our libraries at [Unum](https://github.com/unum-cloud), we have created a specialized package - [SimSIMD](https://github.com/ashvardanian/simsimd), that knows how to use newer hardware capabilities. Compared to SciPy and NumPy, it reaches 3x-200x performance for various data types. Since publication, several LangChain users have asked me if I can integrate it into LangChain to accelerate their workflows, so here I am 🤗 ## Benchmarking To conduct benchmarks locally, run this in your Jupyter: ```py import numpy as np import scipy as sp import simsimd as simd import timeit as tt def cosine_similarity_np(X: np.ndarray, Y: np.ndarray) -> np.ndarray: X_norm = np.linalg.norm(X, axis=1) Y_norm = np.linalg.norm(Y, axis=1) with np.errstate(divide="ignore", invalid="ignore"): similarity = np.dot(X, Y.T) / np.outer(X_norm, Y_norm) similarity[np.isnan(similarity) | np.isinf(similarity)] = 0.0 return similarity def cosine_similarity_sp(X: np.ndarray, Y: np.ndarray) -> np.ndarray: return 1 - sp.spatial.distance.cdist(X, Y, metric='cosine') def cosine_similarity_simd(X: np.ndarray, Y: np.ndarray) -> np.ndarray: return 1 - simd.cdist(X, Y, metric='cosine') X = np.random.randn(1, 1536).astype(np.float32) Y = np.random.randn(1, 1536).astype(np.float32) repeat = 1000 print("NumPy: {:,.0f} ops/s, SciPy: {:,.0f} ops/s, SimSIMD: {:,.0f} ops/s".format( repeat / tt.timeit(lambda: cosine_similarity_np(X, Y), number=repeat), repeat / tt.timeit(lambda: cosine_similarity_sp(X, Y), number=repeat), repeat / tt.timeit(lambda: cosine_similarity_simd(X, Y), number=repeat), )) ``` ## Results I ran this on an M2 Pro Macbook for various data types and different number of rows in `X` and reformatted the results as a table for readability: | Data Type | NumPy | SciPy | SimSIMD | | :--- | ---: | ---: | ---: | | `f32, 1` | 59,114 ops/s | 80,330 ops/s | 475,351 ops/s | | `f16, 1` | 32,880 ops/s | 82,420 ops/s | 650,177 ops/s | | `i8, 1` | 47,916 ops/s | 115,084 ops/s | 866,958 ops/s | | `f32, 10` | 40,135 ops/s | 24,305 ops/s | 185,373 ops/s | | `f16, 10` | 7,041 ops/s | 17,596 ops/s | 192,058 ops/s | | `f16, 10` | 21,989 ops/s | 25,064 ops/s | 619,131 ops/s | | `f32, 100` | 3,536 ops/s | 3,094 ops/s | 24,206 ops/s | | `f16, 100` | 900 ops/s | 2,014 ops/s | 23,364 ops/s | | `i8, 100` | 5,510 ops/s | 3,214 ops/s | 143,922 ops/s | It's important to note that SimSIMD will underperform if both matrices are huge. That, however, seems to be an uncommon usage pattern for LangChain users. You can find a much more detailed performance report for different hardware models here: - [Apple M2 Pro](https://ashvardanian.com/posts/simsimd-faster-scipy/#appendix-1-performance-on-apple-m2-pro). - [4th Gen Intel Xeon Platinum](https://ashvardanian.com/posts/simsimd-faster-scipy/#appendix-2-performance-on-4th-gen-intel-xeon-platinum-8480). - [AWS Graviton 3](https://ashvardanian.com/posts/simsimd-faster-scipy/#appendix-3-performance-on-aws-graviton-3). ## Additional Notes 1. Previous version used `X = np.array(X)`, to repackage lists of lists. It's an anti-pattern, as it will use double-precision floating-point numbers, which are slow on both CPUs and GPUs. I have replaced it with `X = np.array(X, dtype=np.float32)`, but a more selective approach should be discussed. 2. In numerical computations, it's recommended to explicitly define tolerance levels, which were previously avoided in `np.allclose(expected, actual)` calls. For now, I've set absolute tolerance to distance computation errors as 0.01: `np.allclose(expected, actual, atol=1e-2)`. --- - **Dependencies:** adds `simsimd` dependency - **Tag maintainer:** @hwchase17 - **Twitter handle:** @ashvardanian --------- Co-authored-by: Bagatur <baskaryan@gmail.com>	1 year ago

Michael Landis	8e45f720a8	feat: add momento vector index as a vector store provider (#11567) ... **Description**: - Added Momento Vector Index (MVI) as a vector store provider. This includes an implementation with docstrings, integration tests, a notebook, and documentation on the docs pages. - Updated the Momento dependency in pyproject.toml and the lock file to enable access to MVI. - Refactored the Momento cache and chat history session store to prefer using "MOMENTO_API_KEY" over "MOMENTO_AUTH_TOKEN" for consistency with MVI. This change is backwards compatible with the previous "auth_token" variable usage. Updated the code and tests accordingly. **Dependencies**: - Updated Momento dependency in pyproject.toml. **Testing**: - Run the integration tests with a Momento API key. Get one at the [Momento Console](https://console.gomomento.com) for free. MVI is available in AWS us-west-2 with a superuser key. - `MOMENTO_API_KEY=<your key> poetry run pytest tests/integration_tests/vectorstores/test_momento_vector_index.py` **Tag maintainer:** @eyurtsev **Twitter handle**: Please mention @momentohq for this addition to langchain. With the integration of Momento Vector Index, Momento caching, and session store, Momento provides serverless support for the core langchain data needs. Also mention @mlonml for the integration.	1 year ago

Qihui Xie	57ade13b2b	fix llm_inputs duplication problem in intermediate_steps in SQLDatabaseChain (#10279) ... Use `.copy()` to fix the bug that the first `llm_inputs` element is overwritten by the second `llm_inputs` element in `intermediate_steps`. ***Problem description:*** In [line 127]( c732d8fffd/libs/experimental/langchain_experimental/sql/base.py (L127C17-L127C17)), the `llm_inputs` of the sql generation step is appended as the first element of `intermediate_steps`: ``` intermediate_steps.append(llm_inputs) # input: sql generation ``` However, `llm_inputs` is a mutable dict, it is updated in [line 179](https://github.com/langchain-ai/langchain/blob/master/libs/experimental/langchain_experimental/sql/base.py#L179) for the final answer step: ``` llm_inputs["input"] = input_text ``` Then, the updated `llm_inputs` is appended as another element of `intermediate_steps` in [line 180](c732d8fffd/libs/experimental/langchain_experimental/sql/base.py (L180)): ``` intermediate_steps.append(llm_inputs) # input: final answer ``` As a result, the final `intermediate_steps` returned in [line 189](c732d8fffd/libs/experimental/langchain_experimental/sql/base.py (L189C43-L189C43)) actually contains two same `llm_inputs` elements, i.e., the `llm_inputs` for the sql generation step overwritten by the one for final answer step by mistake. Users are not able to get the actual `llm_inputs` for the sql generation step from `intermediate_steps` Simply calling `.copy()` when appending `llm_inputs` to `intermediate_steps` can solve this problem.	1 year ago
Florian	d78f418c0d	Extract abstracts from Pubmed articles, even if they have no extra label (#10245) ... ### Description This pull request involves modifications to the extraction method for abstracts/summaries within the PubMed utility. A condition has been added to verify the presence of unlabeled abstracts. Now an abstract will be extracted even if it does not have a subtitle. In addition, the extraction of the abstract was extended to books. ### Issue The PubMed utility occasionally returns an empty result when extracting abstracts from articles, despite the presence of an abstract for the paper on PubMed. This issue arises due to the varying structure of articles; some articles follow a "subtitle/label: text" format, while others do not include subtitles in their abstracts. An example of the latter case can be found at: [https://pubmed.ncbi.nlm.nih.gov/37666905/](url) --------- Co-authored-by: Bagatur <baskaryan@gmail.com>	1 year ago

Theron Tau	35297ca0d3	Add feature for extracting images from pdf and recognizing text from images. (#10653) ... **Description** It is for #10423 that it will be a useful feature if we can extract images from pdf and recognize text on them. I have implemented it with `PyPDFLoader`, `PyPDFium2Loader`, `PyPDFDirectoryLoader`, `PyMuPDFLoader`, `PDFMinerLoader`, and `PDFPlumberLoader`. [RapidOCR](https://github.com/RapidAI/RapidOCR.git) is used to recognize text on extracted images. It is time-consuming for ocr so a boolen parameter `extract_images` is set to control whether to extract and recognize. I have tested the time usage for each parser on my own laptop thinkbook 14+ with AMD R7-6800H by unit test and the result is: | extract_images | PyPDFParser | PDFMinerParser | PyMuPDFParser | PyPDFium2Parser | PDFPlumberParser | | ------------- | ------------- | ------------- | ------------- | ------------- | ------------- | | False | 0.27s | 0.39s | 0.06s | 0.08s | 1.01s | | True | 17.01s | 20.67s | 20.32s | 19,75s | 20.55s | **Issue** #10423 **Dependencies** rapidocr_onnxruntime in [RapidOCR](https://github.com/RapidAI/RapidOCR/tree/main) --------- Co-authored-by: Bagatur <baskaryan@gmail.com>	1 year ago

It lives in `docs/extras` directory. If no one reviews your PR within a few days, please @-mention one of @baskaryan, @eyurtsev, @hwchase17. --> ## Description Currently SQLAlchemy >=1.4.0 is a hard requirement. We are unable to run `from langchain.vectorstores import FAISS` with SQLAlchemy <1.4.0 due to top-level imports, even if we aren't even using parts of the library that use SQLAlchemy. See Testing section for repro. Let's make it so that langchain is still compatible with SQLAlchemy <1.4.0, especially if we aren't using parts of langchain that require it. The main conflict is that SQLAlchemy removed `declarative_base` from `sqlalchemy.ext.declarative` in 1.4.0 and moved it to `sqlalchemy.orm`. We can fix this by try-catching the import. This is the same fix as applied in https://github.com/langchain-ai/langchain/pull/883. (I see that there seems to be some refactoring going on about isolating dependencies, e.g. c87e9fb2ce, so if this issue will be eventually fixed by isolating imports in langchain.vectorstores that also works). ## Issue I can't find a matching issue. ## Dependencies No additional dependencies ## Maintainer @hwchase17 since you reviewed https://github.com/langchain-ai/langchain/pull/883 ## Testing I didn't add a test, but I manually tested this. 1.

Removes human prompt prefix before system message for anthropic models Bedrock anthropic api enforces that Human and Assistant messages must be interleaved (cannot have same type twice in a row). We currently treat System Messages as human messages when converting messages -> string prompt. Our validation when using Bedrock/BedrockChat raises an error when this happens. For ChatAnthropic we don't validate this so no error is raised, but perhaps the behavior is still suboptimal	1 year ago
Massimiliano Angelino	2f83350eac	Feat bedrock cohere support (#11230) ... **Description:** Added support for Cohere command model via Bedrock. With this change it is now possible to use the `cohere.command-text-v14` model via Bedrock API. About Streaming: Cohere model outputs 2 additional chunks at the end of the text being generated via streaming: a chunk containing the text `<EOS_TOKEN>`, and a chunk indicating the end of the stream. In this implementation I chose to ignore both chunks. An alternative solution could be to replace `<EOS_TOKEN>` with `\n` Tests: manually tested that the new model work with both `llm.generate()` and `llm.stream()`. Tested with `temperature`, `p` and `stop` parameters. **Issue:** #11181 **Dependencies:** No new dependencies **Tag maintainer:** @baskaryan **Twitter handle:** mangelino --------- Co-authored-by: Harrison Chase <hw.chase.17@gmail.com>	1 year ago

Description: Similar in concept to the `MarkdownHeaderTextSplitter`, the `HTMLHeaderTextSplitter` is a "structure-aware" chunker that splits text at the element level and adds metadata for each header "relevant" to any given chunk. It can return chunks element by element or combine elements with the same metadata, with the objectives of (a) keeping related text grouped (more or less) semantically and (b) preserving context-rich information encoded in document structures. It can be used with other text splitters as part of a chunking pipeline.

Predrag Gruevski	42d979efdd	Improve type hints and interface for SQL execution functionality. (#11353) ... The previous API of the `_execute()` function had a few rough edges that this PR addresses: - The `fetch` argument was type-hinted as being able to take any string, but any string other than `"all"` or `"one"` would `raise ValueError`. The new type hints explicitly declare that only those values are supported. - The return type was type-hinted as `Sequence` but using `fetch = "one"` would actually return a single result item. This was incorrectly suppressed using `# type: ignore`. We now always return a list. - Using `fetch = "one"` would return a single item if data was found, or an empty *list* if no data was found. This was confusing, and we now always return a list to simplify. - The return type was `Sequence[Any]` which was a bit difficult to use since it wasn't clear what one could do with the returned rows. I'm making the new type `Dict[str, Any]` that corresponds to the column names and their values in the query. I've updated the use of this method elsewhere in the file to match the new behavior.	1 year ago
